Title: Continuous optical fibre damping measurement during coating - by comparing scattered light measurements before and after coating with protective plastics layer
Inventor: SCHILDBACH KLAUS DR
IPC: G01M11/00
Filed: 1979-08-11
Abstract: An arrangement continuously measures the damping of optical fibres during processing, esp. during coating with a protective plastics layer. A light signal (8) is applied to one end of the fibre wound on a drum (2). The relatively small damping variations, arising e.g. as a result of the plastics surface irregularities are reliably determined without interrupting the process. Coupling devices (5,6) are placed either side of the processing point (3). The fibre (1) passes through the couplers, each of which measures the scattered light. The corresp. coupling device output signals are compared. The light source (8) is a pulsed semiconductor laser. The coupling devices (5,6) either side of the processing point contain several light sensitive semiconductor elements each partially enclosing the fibre. Their outputs are fed to an electronic divider (9).

Abstract: A digital circuit is used to drive a light emitting diode (LED) display arrangement has a piece of ornamental 'jewellery'. The LED display may be arranged in the form of a heart or cross etc. In basic form an array of diodes are coupled to the outputs of two multi-stage binary counters operated off separate clock sources. One set of counter outputs are coupled to the cathodes of the LED stages and the other outputs to the anodes. When a cathode high -anode low state exists the LED is active. By varying the counter clock rates a range of display patterns are produced. To create a specific pattern, a matrix of LED elements are used with the two counters coupled to the rows and columns of the matrix.

Title: Mechanical speech reproducer for fault warning in car - has stylus tracing spiral groove on disc with automatic stop and repeat facility
Inventor: TSUNODA MASAKAZU
IPC: B60R16/037
Filed: 1980-10-02
Abstract: A fault condition in a car turns on a transistor which starts an electric motor and mechanically reproduces a spoken message, e.g. 'The light is still switched on'. The motor drives a belt round the rim of a disc which is free to rotate and slide on a fixed shaft. The message is recorded in a spiral groove on one face of the disc. A spring on the shaft presses the disc against a stylus on a pivoted tone-arm so that it follows the groove. The other side of the tone-arm presses against the back of a loudspeaker cone. After the message, the tone-arm follows the groove inwards and pushes a stop lever inwards to engage a cam in the centre of the disc. The cam pushes the disc away from the stylus and a switch opens the motor circuit, unless it is still closed by the transistor. The tone-arm returns to the outside of the disc by a spring. The message then repeats until the fault is corrected.

The filtered polymer has a low content of diluent. The catalyst residues do not have to be removed; they degrade during stabilisation of the polyoxymethylene and gps. e.g. esterification or etherification. Polymerisation can be carried out continuously.
